COKE-DRAWING APPARATUS.

' Specification of Letters Patent.

Patented. Oct. 6, 1908.

Application filed May 2, 1307. Serial No. 371,392.

To all whom it may concern:

Be it known that 1, JAMES REED, a citizen of the United States of America, residing at Drawing Apparatus, of which the following is a specification, referencebeing hadtherein to the accompanying drawing.

This invention relates to improvements in coke drawing apparatus, and the invention has for its object to provide novel cokeovens and an apparatus for-drawing coke from the bottom of said ovens. v

My invention aims to provide coke ovens of novel construction, which can be easily and quickly filled, and the coke removed from the bottom of the ovens. In this con-'- nection, I have devised a novelapparatusj adapted to travel beneath the ovens and lower the bottom or vbase of each of the:

ovens, the apparatus being-constructed to tilt the base of each of the ovens anddischarge e the coke therefrom. To this end, I provi a steel structure adapted to support ovens in an elevated position, track-way being arranged above the ovens for discharging coal into the same. Each oven is provided with a detachable bottom or base and adapted to travel beneath theovens is an apparatus,

consisting principally of'a hydraulic cylin der having a tilting head, which is tempo-- rarily secured to the base of each of the ovens, when it is desired to lower the base and dischar e the coke carried thereby;

The detai construction entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to the drawings forming a part of this specification, like numerals designate corresponding parts throughout the several views, in which: v p

Figure 1 isan elevation of my improved apparatus, illustrating coke ovens in section, Fig. 2 is a plan of a coke oven constructed in accordance with my invention, Fig. 3 is an end view of the apparatusillustratinga coke oven in section, Fig. 4 is a perspective view of a portionofa detachable base of an oven, Fig. 5 is a plan of the same.

To put my invention into practice, I con-- struct an elevated trackway 1 supported upon columns or standards 2. The columns or standards 2 are provided with longitudinal girders 3 and transverse beams 4,},the

girders and beams being arranged approximately midway of the base of the standards or columns 2 and the elevated track-way 1.-

The girders 3 and the beams 4 support con- 'ical-shaped ovens 5 constructed of any suitable material and having coal inlet openings 6 and door-ways 7, said door-ways being normally closed.

Each oven is provided with a detachable I circular base 8 of any suitable material but preferably the base 8 is formed of boiler steel with interlocking fire brick, the brick is interlocked so that when the base is tilted it will-not become disengaged from the frame which constitutes an element of the base. The base is normally held in the oven by clamps'Q engaging the beams 4 of the coke oven supporting structure. The clamps are provided with depending chains or cables 10,

whereby said clamps can be swung out of engagement with the beams at any time it is desired to remove the base from the oven. The base of each oven is provided with up- -wardly extending sides or flanges 11, which are cutaway as at 12 to clear the beams 4 and the girders 3, and as at 13 to clear the clamps 9. The flanges llare employed to prevent the coke from falling from the base 8, when thesameis lowered, as will be presently described.

'Beneath the coke ovens 5 is arranged a track 14, upon which is movably mounted a truck 15, said truck carrying a conventional forni ofboiler 16, an engine 17, and a ram comprising thecylinder 18 and a piston 19. A .pipeld leads from the boiler 16 to the cylinder 18'for conveying steam to the ram. The piston 19 of said ram is provided with a trunnioned ,head 20, said head carrying the hook-shaped levers 21 for engaging pins 22 carried by the base 8, of each oven. The hook-shaped levers 21 areprovided with depending chains or cables 23 whereby the levers can be easily and quickly manipulated from the truck 15.

To tilt the heads 20, when lowered, E provide thetruck 15"with bearings 24 on which are journaled shafts 25 carrying drums 26, and sprocket wheels 27 ,said sprocket wheels being connected by chains 28 with sprocket wheels 29, the latter being 'journ-aled upon the truck 15 and driventhrough the medium of a-crank disk 30 operated from the engine .17. The drums 26 are connected by chains v or cables 31. to the. diametrically opposed sides of the head 20, whereby. when the drums .26 are rotated, the head '20 can be tilted in any desired direction to and including snfiieient distance to discharge the coke from the base 8; held in engagement with the head 20 by the hook-shaped levers 21. Suitable mechanism (not shown) can be employed for controlling the direction of rotation of the drums 26, and the engine 17 can be of a reversible type.

Upon the track-way 1 is adapted to travel cars 32 having-dro 3 doors 3;) for discharging coal into the opening (3 of the ovens Operations The truck 15 is moved upon the track 14 to position the cylinder 18' beneath the oven from which coke is to be drawn. The head 20 carried by the piston 19 of the cylinder is moved into engagement with the base 8 of the oven 5 and clamped thereto by the hook-shaped levers 21. The clamps 9 are then released, whereby when the piston 19 is lowered, the base 8 will be carried downwardly and with it. the coke contained within the ovens 5. After the head has been lowered a suflicient distance, the engine 17 is placed in operation to rotate the drums 26 and tilt the head and the base carried thereby, to discharge the coke from said base. After the coke has been discharged, the head 20 can be placed upon a horizontal plane, and elevated, and the base 8 again clamped to the beams l, and the head 20 released from engagement with said base. The truck 15 can then be moved to the next oven and the same operation repeated.

It will be apparent from the illustration of my invention that I have devised a novel coke oven supporting structure and an apparatus for easily and quickly d 'awing coke from the ovens.

I do not care to conliue myself to the structural details illustrated, but such mod i fications of my invention as are permissible by the appended claims may be resorted to without departing from the spirit and scope of the invention.

Having fully described my invention what I claim and desire to secure by Letters said ovens, upwardly extended flanges carried upon said trucl-z. chains connecting said drums with said head. and means for operating said drums to tilt said head and the base attached thereto.

2. In a coke drawing apparatus. the combination of elevated coke ovens, detachable bases connected to said ovens, upwardly extended flanges carried by said base, a truck adapted to travel beneath said ovens, a ram carried by said truck, a head trunnioned upon the piston ot' the ram, hook-shaped levers connecting said head to the base of an oven. drums located upon said truck, chains connecting said drums with said head, and

means for operating said drums to tilt said head and the base attached thereto.

3. In a coke drawing apparatus, the combination of elevated coke ovens, a detachable base carried by each oven, a truck movable beneath said ovens, a ram carried by said truck, a head trunnioned upon the piston of the ram, drums carried by said truck and connecting with the diametrically opposed sides of said head, means to clamp said head to the base of an oven, and means carried by said truck for operating said drums to tilt said head.

4. In a coke drawing apparatus. the combination of elevated coke ovens, a se dctachably connected to each oven, a truck adapted to travel beneath said ovens, a head supported from said truck and adapted to be detachably connected to the base of an oven. means carried by said truck for raising and lowering said head, and means for tilting said head.

5. The combii'iation with a coke oven, ot a base detachably connected to said oven, a head adapted to be detachably connected to said base. means movable beneath said oven for raising and lowering said head, and means for tilting said head.

6. The con'ihination with a coke oven having a removable bottom, of a reciprocatory member provided with a pivoted head detachably connected with the bottom.

7. The combination with a. coke oven having a removable bottom, ot a reciprocatory member provided with a pivoted head de-' tachably connected with the bottom, and means whereby said bottom can be tilted when lowered.

In testimony whereof afiix iuv signature in the presence of two witnesses.

JAMES REED.
